ABSTRACT:
A disk drive suitable for receiving removable, cartridge-based media including a movable shutter, comprising a cartridge holder having a bottom guiding area divided into two sections along the side of the cartridge, along with a shutter guide formed therebetween near a central rotary drive used to position the media within the cartridge. The shutter guide guides the cartridge shutter upward from the central rotary drive when a cartridge is either being inserted into or extracted from the holder. Therefore, the cartridge can always be extracted even when the cartridge shutter comes close to the rotary drive due to its own weight and without being directly guided by the cartridge holder. Furthermore, the shutter guide is preferably formed protruding toward the central rotary drive and disposed adjacent thereto, it is possible to guide the cartridge shutter only when it passes near the rotary drive during cartridge extraction, and thus no undue force is applied to the cartridge when it is positioned for read/write access.
